MeiraGTx and Hologen AI Form $430 Million Strategic Collaboration to Advance Parkinson's Disease Gene Therapy

  • MeiraGTx has secured a strategic collaboration with Hologen AI that includes a $200 million upfront payment and the formation of a joint venture with an additional $230 million in committed capital to advance AAV-GAD gene therapy for Parkinson's disease.

  • The partnership creates the first neuro-AI clinical drug development company, combining MeiraGTx's gene therapy expertise with Hologen's AI technology to transform CNS drug development for neurodegenerative and neuropsychiatric disorders.

  • Recent clinical data showed AAV-GAD therapy demonstrated significant benefits in Parkinson's disease patients, with meaningful improvements in motor function (UPDRS Part 3) and quality of life measures (PDQ-39).

MeiraGTx Holdings plc (Nasdaq: MGTX) has announced a landmark strategic collaboration with Hologen AI that includes a $200 million upfront payment and the formation of a joint venture with an additional $230 million in committed capital. The partnership, revealed during MeiraGTx's fourth quarter and full-year 2024 financial results announcement, aims to accelerate the development of gene therapies for neurological disorders, with an initial focus on AAV-GAD for Parkinson's disease.

Strategic Collaboration Details

The newly formed joint venture, Hologen Neuro AI Ltd, represents the first neuro-AI clinical drug development company in the industry. MeiraGTx will maintain 30% ownership in the venture while leading all clinical development and manufacturing activities. Hologen will contribute its proprietary multi-modal generative foundation models (LMMs) to enhance clinical trial design and execution.
"This extraordinary progress has continued in 2025 with today's announcement of a strategic collaboration with Hologen," said Alexandria Forbes, Ph.D., president and chief executive officer of MeiraGTx. "The joint venture will initially be focused on increasing the robustness, efficiency and probability of success of the AAV-GAD Phase 3 clinical study."
The collaboration extends beyond the joint venture, with Hologen also acquiring a minority stake in MeiraGTx's manufacturing subsidiary. This arrangement includes commitments for Hologen to deploy its AI capabilities to optimize MeiraGTx's proprietary manufacturing processes.

Promising Results for AAV-GAD in Parkinson's Disease

The partnership builds on positive clinical data announced in October 2024 from a randomized, sham-controlled clinical bridging study of AAV-GAD for Parkinson's disease. The therapy met its primary safety and tolerability objectives while demonstrating significant efficacy:
  • Patients in the high-dose group showed an 18-point improvement in the Unified Parkinson's Disease Rating Scale (UPDRS) Part 3 at 26 weeks (p=0.03)
  • Both high and low dose groups experienced significant improvements in the Parkinson's Disease Questionnaire (PDQ-39), a key quality of life measure
Dr. Forbes noted that Hologen's AI technology, when applied to MeiraGTx's Phase 2 clinical data, "has already significantly de-risked the AAV-GAD program and identified disease modifying changes in the physiology of the brain in response to AAV-GAD treatment."

Advancing Multiple Gene Therapy Programs

Beyond the Parkinson's disease program, MeiraGTx reported progress across its gene therapy pipeline:

AAV2-hAQP1 for Radiation-Induced Xerostomia (RIX)

The FDA granted Regenerative Medicine Advanced Therapy (RMAT) designation for AAV2-hAQP1 in December 2024 for the treatment of Grade 2/3 RIX. This designation provides benefits similar to Fast Track and Breakthrough Therapy designations, including increased FDA interactions and potential accelerated approval pathways.
"AAV2-hAQP1 was granted Regenerative Medicine Advanced Therapy designation for Grade 2/3 RIX in December 2024 by the U.S. Food and Drug Administration, reinforcing the strength of our clinical data and its potential to significantly improve the lives of xerostomia patients," Dr. Forbes stated.
The company has aligned with the FDA on requirements for its ongoing Phase 2 AQUAx2 clinical trial to serve as a pivotal study supporting a potential Biologics License Application (BLA) filing in 2026.

rAAV8.hRKp.AIPL1 for LCA4 Retinal Dystrophy

In February 2025, MeiraGTx announced publication of efficacy data for rAAV8.hRKp.AIPL1 in The Lancet. The therapy showed unprecedented responses in 100% of children with LCA4, one of the most severe forms of inherited blindness.
"The results from these 11 young children are truly remarkable and unrivalled in treatment benefit," said Dr. Forbes. "With these truly exceptional clinical results in hand, along with our in-house manufacturing process, we anticipate filing with the UK's Medicines and Healthcare products Regulatory Agency (MHRA) for approval under exceptional circumstances."
The company plans to pursue parallel regulatory pathways with the FDA and other global regulators to expedite access to this therapy for LCA4 patients worldwide. The FDA has granted Rare Pediatric Disease Designation (RPDD) to this program, along with three other MeiraGTx inherited retinal disease therapies.

Botaretigene Sparoparvovec (bota-vec) for X-linked Retinitis Pigmentosa

Data from the Phase 3 LUMEOS trial of botaretigene sparoparvovec for X-linked retinitis pigmentosa, developed in collaboration with Johnson & Johnson Innovative Medicine, is expected in 2025. MeiraGTx is eligible to receive up to $285 million upon first commercial sales in the U.S. and EU, along with manufacturing technology transfer milestones.

Manufacturing Capabilities Expansion

MeiraGTx has strengthened its end-to-end manufacturing infrastructure with additional clinical and commercial licensures in Ireland and the UK:
  • The UK facility holds authorizations for manufacturing, fill-finish, and QC testing of both investigational and 'Special' medicinal products
  • The Shannon, Ireland facility recently received viral vector manufacturing authorization, making it the first gene therapy facility in Ireland with such a license
"MeiraGTx has built the most comprehensive manufacturing capabilities in the industry, with 5 facilities globally, including two that are licensed for GMP viral vector production and a GMP QC facility with clinical and commercial licensure," the company noted in its announcement.

Financial Position

As of December 31, 2024, MeiraGTx reported:
  • Cash and cash equivalents of $103.7 million
  • $0.7 million in receivables from Johnson & Johnson Innovative Medicine
  • $6.8 million in tax incentive receivables
With the $200 million upfront payment from Hologen, the company expects to have sufficient capital to fund operations into 2027, including repayment of its $75 million debt obligation to Perceptive Advisors due in August 2026.
For the full year 2024, MeiraGTx reported:
  • Service revenue of $33.3 million
  • Research and development expenses of $119.5 million
  • General and administrative expenses of $54.2 million
  • Net loss of $147.8 million, or $2.12 per share

Future Outlook

The collaboration with Hologen AI represents a significant strategic shift for MeiraGTx, positioning the company at the intersection of gene therapy and artificial intelligence. By combining MeiraGTx's clinical-stage genetic medicines with Hologen's AI capabilities, the partnership aims to transform the discovery and development of therapies targeting CNS circuitry.
"In forming this joint venture, MeiraGTx and Hologen have created the first neuro-AI clinical drug development company in which pioneering technologies from both companies will be deployed to transform the discovery and development of therapies targeting CNS circuitry," Dr. Forbes explained. The goal is to "advance the development of drugs with meaningful impact on neurodegenerative and neuropsychiatric diseases which have been largely intractable to effective treatment to date."
With multiple late-stage programs advancing toward potential regulatory approvals and a strengthened financial position, MeiraGTx appears well-positioned to continue its innovation in genetic medicine while addressing significant unmet medical needs.
